It's so hard to know what the end result will be.
They are very cryptic, they dismiss legitimate concerns with cries of bias or "you just haven't seen the data."
Their board is all politicians and military types. No lab experts?
The founder makes a lot of statements with comparisons to current lab practice that are woefully incorrect (it takes a week to get test results back, you can't run reflex tests, you need one tube of blood for every test).
They make vast claims about what frequent and early lab testing can do (catch your pancreatic cancer 10 years early and be cured!), and dismiss concerns about any of this overtesting.
I suspect they are using their market value and buzz to build up a business big enough to be sustained when they have to do these public comparisons.
It certainly seems like a legitimate company with a lot to offer. To me it seems like their biggest contribution will be the "democratization" of the lab test and helping to push down costs and prices. Getting smaller samples on less invasive collection systems would definitely be beneficial for people who need frequent testing for whatever reason (diabetics, renal patients, chemo pts, etc). But there are significant questions about how this would be applied to hospitalized (sick!) patients for whom finger sticks might be less accurate.
Also, because they are proprietary they can't put their machines in hospitals yet. So for now their reach will be limited, but will likely grow. The question is how far. Will they remain a niche or will they truly revolutionize? The current business and practice patterns favor the former (albeit maybe a large niche) but the jury is obviously still out.
It is definitely good to see the media focusing more critically on it. The financial bloggers and sites are starting to put more scruitiny into it, which is definitely a welcome change from the previous months of articles basically saying, "This 30 year old woman is a billionaire" "This tech billionaire is just like steve jobs, but a woman!" "This self made billionaire is going to upend the lab business!" If they really admired her they would focus less on her appearance and her bank account.
